and Adjustments” in the PDF Service Guide

.

After the specified adjustments have been performed, the analyzer should
operate and phase lock over its entire frequency range.

EEPROM Backup

The analyzer uses arrays of correction constants to enable the analyzer to
produce accurate, leveled source signals and receive clean test signals. These
constants are stored in non-volatile EEPROM memory and in flash memory
files.

The adjustments listed here generate new correction constants. The analyzer
must have a backup of this new data in case any of the data becomes
corrupted.

To store the backup data, perform these steps:

— Navigate to the EEPROM Backup Utility, located at:

— Windows 7 -- C:\Program Files (x86)\Keysight\Network

Analyzer\Service\eebackup.exe

— Windows 10 -- C:\Program Files\Keysight\Network

Analyzer\Service\eebackup.exe

— Run the program.
